UNMEB STAR@ Sina JOSEPH M. DRUECKER, OF STONE CITY, IOWA.

Application filed June 30, 1916. Serial No. 106,767.

To all whom t may concern Be it known that I, Josnrir M. Dnnnonnn, acitizen of the United States, and resident of Stone City, in the countyof J ones and State of Iowa, have invented certain new and usefullimprovements in Auton'iatie Dumping and Righting Mechanisms forTilt-able Dump-Cars; and 1 do hereby declare that the following is afull, clear, and exact description thereof.

The present invention relates to` new and useful vimprovements intiltable dump cars, and is more particularly directed to the provisionof means for procuring dumping movements of such cars.

lt is primarily the object of the invention to provide a means forautomatically dumping tiltable cars upon their reaching a certaindesired position, and for automatically righting the cars upon theirbeing moved away from said dumping position.

lt is more specifically an object to provide an automatic dumping meansso associated with the cars that the cars are normally held "1 againstpossible accidental tilting.

It is still further an object to Yprovide an automatic dumping mechanismof the present nature Which is of exceedinglysimple structure and whichmay be associated Awith various types of dump cars now in common usewith but very slight modification of the structure thereof.

W ith the above and other objects and advantages in View the inventionresides more particularly in the novel combination, ar-

rangement and formation of parts more particularly hereinafter describedand more particularly pointed out in the appended claims. y

Figurel 1 is a side elevational view of a tilting railway dump' car,having the improved automatic dumping and righting mechanism associatedtherewith. v

F i g. 2 is a transverse sectional view on the line 2-2 of Fig. 1. y

F 3 is a detailed sectional view showing a trip member, this view beingindicated by the line 3 3 of Fig. 1.

Referring now more particularly to the accompanying drawings, 5designates each of a pair of rails on which is mounted a tiltn ing sidedump car of the type commonly used in conveying earth or like materialand l which comprises the Wheeled base frame 6 provided With alongitudinal series of pivot bearings 7 for plvotally mounting the carSpecification of Letters Patent.

body 8. The usual means of holding the car body against tilting is bychains secured to the sides of the body and to the sides of the baseframe, and to adapt the car for use in connection with the presentautomatic dumping' mechanism, only the chains at the side of the carbody at which it is desired to dump are retained, these chains beingdesignated at 9. To provide a clearance for aportion of the automaticdumping mechanism, the lever mechanism for opening the opposite side ofthe car is also removed, the lever mechanism at the dump side of thecar, designated at 10, being retained.

To hold the lifting side of the car against upward tilting' movement, ina manner providing for the ready automatic release of said side of thecar, a U-shaped link member 11 pivotally depends from the centralportion of said side of the car, and has its bight ei'igageable in ahook plate 12 carried by the adjacent side of the base flange 6. Thislink is normally held in engagement With the hook by a retractile spring13 secured to the car side and to the intermediate portion of the link,and the link is held against undesired swinging movement by this springwhen disengaged from the hook, by a chain 14 secured thereto and to thecar side. The top of the hook plate 12 is inclined down- Wardly towardthe hook opening and thus provides for an automatic locking engag mentof the link with the hook upon swinging movement of the car body back torighted position.

F or automatically dumping the car, the lifting side of the forward endthereof carries a laterally projected dumping arm 15 which is engageablewith an upwardly inclined beam 16 disposed along the track and theholding link 11 is released immediately prior to the engagement of thedumping arm with the inclined beam by means of a trip arm 17 which ispivotally mounted on an upstanding shaft 18, this shaft being preferablysecured at its lower end to the lower end of the inclined beam 16 andsecured at its upper end to a horizontal bracket arm '19 carried by saidbeam, a second bracket arm 20 having a seating recess 21 at its endbeing engageable with the intermediate portion of the trip member tohold it for proper engagement With the link. By this structure the barmay be swung out of the Way when not in use, to permit the passage o-fordinary traflic over the rails, it being understood that the inclineddumping beam and the righting beam later to be described are spacedsuliiciently from the rails toprovide a proper clearance for traflic.

Thus, to automatically dump the car, it is moved toward the dumping beamand trip bar, and the trip bar engages the lever and swings it from thehook to release the body of the car for tilting movement. The dump arml5 then engages the inclined beam 16 and rides upwardly thereon to dumpthe car.

.For righting` the car, an arm Q2 projects laterally from the depressingside of the rear endof the car, and this arm, when the car is tilted, isadapted to engage an inclined righting beam 23 disposed along the track.

In the structure illustrated the righting beam 23 is disposed to therear of the car in its dumping position, and inclined downwardly towardthe dumping beam. Thus upon the car being moved to dumping position, andthen moved backwardly, a righting of the car body will be effected.

From the foregoing` it is seen that an exceedingly simple arrangementhas been procured whereby tilting dump cars may be dumped, and rightedautomatically, upon movement of the cars toward and awal f from adesired dumping position.

The preferable method of securing the vertical leg of the inclinedrighting beam 16 is by bolting said leg to the extended end of atransverse rail 2li disposed under the track rails 5 and connectedtherewith by suitable gripping dogs 25, an exceedingly rigid structurebeing thus procured.

Ihile I have described my present invention for use in connection withside dump cars, and adapted to dump said cars and right themuponmovement forwardly and rearwardly with respect to a certainposition, it is obvious that in as much as the essential feature of myinvention resides in the provision of dumping and righting meansdisposed at opposite sides of the pivotal axis of a car, and a releasingmeans operative prior to engagement of the car with the dumping means,various structures embodying this essential feature may be providedwithout departing from the spirit of the present invention asinterpreted by the accompanying claims.

I claim:
